Chemical Microscopy Sample Dataset for Evaluation — by Mendeln J

Author: Giorgi Japaridze
Version: 1.0
License: Custom, non-redistributable, evaluation-only sample

🧪 Overview

This repository contains a small, representative sample of a larger 10-year archive of high-resolution chemical microscopy experiments.
This sample represents only a very small portion of the full archive.

The complete dataset contains several thousand high-resolution RAW microscopy images and more than 1,000 4K and HD video recordings, documenting a wide range of chemical crystallization and reaction phenomena. The full dataset can be made available under a separate licensing agreement.

The sample demonstrates a diverse range of microscale chemical behaviours:

• crystalline and non-crystalline structures
• nucleation, dendritic & non-dendritic growth
• dissolution processes
• thin-film evaporation & fluid front dynamics
• reaction interfaces & multiphase interactions
• varying illumination responses (brightfield / darkfield / cross-polarized)

This dataset is intended solely for evaluation and partner discussions regarding a training-only, non-redistributable license.
It is not an open-source dataset and not permitted for redistribution.

🧬 Metadata Schema

Demo_Dataset/Metadata/demo_metadata.csv contains one row per file, describing the essential technical and chemical context.

Fields

• filename – relative path within the dataset
• type – "image" or "video"
• technique – brightfield, darkfield, or polarized
• is_stacked – no, stack_final, or stack_frame
• chemical_main – primary compound
• chemical_secondary (optional) – additives / mixed systems
• solvent_main – primary solvent (water, ethanol, acetone, n-propyl alcohol, ammonia–water, etc.)
• solvent_secondary (optional) – modifiers (DMSO, acetic acid, glycerin, etc.)

---

🔬 Optical & Capture Setup

All media in this sample was captured using:

Camera

• Canon R5 Mark II (RAW stills + high-quality video)

Optics

• Microscope objectives at varying magnifications
• Extreme-macro sequences using microscope objectives + Laowa macro lenses

Illumination Modes

• Transmitted brightfield
• Transmitted darkfield
• Cross-polarized light

Full Archive Includes

• Several thousand RAW still images
• 1000+ 4K and HD videos
• Thousands of extreme-macro individual frames and stacks in RAW format

⭐ Applications & Use Cases

Microscopy datasets depicting chemical reactions, crystallization dynamics, and polarized thin-film behaviour are rare and current models do not produce realistic imagery/dynamics/lighting etc.
Full dataset can be used for model training:

• micro-scale physical processes difficult to simulate
• reaction kinetics and nucleation behaviour
• complex fractal and dendritic morphologies
• transitions between crystalline, amorphous, and fluid states
• multimodal imaging (brightfield / darkfield / polarized)
• high-resolution 4K temporal data

🔒 Intended Use & Licensing

This sample is provided for internal evaluation only, under a custom, non-redistributable license.

• The author retains full copyright
• Data may be used internally for model training & evaluation
• Original media may not be redistributed or exposed to end users
• No republishing, resale, or public sharing of media files
• Full dataset access requires a separate licensing agreement

A much larger dataset (thousands of images & high-resolution videos) is available for partnership discussions.
